Endorsements

An endorsement allows you to operate a certain type of commercial motor vehicle and transport specific items. There is additional testing required to obtain an endorsement and, in some cases, you will be required to hold a commercial learner permit (CLP) for that endorsement for at least 14 days before being able to add it to your CDL. Additional training, called the Entry Level Driver Training, is required after February 7, 2022.

​

The types of endorsements you can apply for are listed in the chart below:
